一种双输入光伏逆变器辅助电源供电系统
摘要：
本实用新型公开了一种双输入光伏逆变器辅助电源供电系统，包括第一输入隔离变换装置，还包括第二输入隔离变换装置、第三输入隔离变换装置和储能电路，所述第一输入隔离变换装置和第二输入隔离变换装置的输入端均与高压输入源连接且输出端均连接有直流220V母线，第三输入隔离变换装置的输入端与直流220V母线相连且输出端与储能电路相连，所述直流220V母线与第一负载电路相连且储能电路与第二负载电路相连。既能解决大功率冲击性负载的电源容量需求问题，减小供电系统容量从而降低电源成本，又能保证低电压穿越期间控制系统供电的持续性。
摘要（英）：

The utility model discloses a dual input photovoltaic inverter auxiliary electrical power source power supply system, including an input isolation converting means, still include the 2nd input isolation converting means, the 3rd input isolation converting means and tank, an input isolation converting means and the 2nd input isolation converting means's input all is connected with high -pressure input source and the output all is connected with direct current 220V generating line, the 3rd input isolation converting means's input and direct current 220V generating line links to each other and the output links to each other with tank, continuous just tank of a direct current 220V generating line and a load circuit and the 2nd load circuit link to each other. Can solve the power capacity requirement problem of high -power impact nature load, thereby it the power cost is reduced to reduce the power supply system capacity, the continuation of control system power supply during the low voltage ride through can be guaranteed again.
